We have 1 unit of 2900 series router and 3 FE interfaces. One interfaces is used as sub-interface (We have 2 IP segment that used this router as their gateway) and other 2 ports as internet link connected to router's provider.
ISP give us 1 Public IP and another ISP give us 1 public address two.
The two internet links is used as active-standby link.
Can you guide how ip nat configuration against this scenario please?
